You don't really need it, but if you don't use it, you will have to look for drivers and manually take care of them. With that said, sometimes they deprecate those watchdogs and they end up doing nothing at all after a year or so...

Disable it, don't delete it, and you can always turn it on periodically.

Most likely, you won't need it. Heck, even in server environments, I disabled it after a few unwarranted reboots (obviously, they can be called unwarranted only if the server is very stable for longer periods, before or after you've disabled this feature)
